Classified advertising is that advertising which is grouped in certain sections of the paper and is thus distinguished from display advertising. Such groupings as “Help Wanted”, “Real Estate”, “Lost and Found” are made, the rate charged bei ng less than for display advertising. Classified advertisements are a convenience to the reader and a saving to the advertiser.

The reader who is interested in a particular kind of advertisement finds all advertisements of that type grouped for him. The advertisers may, on this account, use a very small advertisement if it were placed among larger advertisements in the paper. It is evident that the reader approaches the classified advertisement in a different frame of mind from that in which he approaches the other advertisements in the paper.

Formerly all classified advertisements were of the same size and did not have display type. With the increase in the number of such advertisements, however, each advertiser within a certain group is competing with others in the same group for the reader’s attention. In many cases, the result has been an increase in the size of the space used and the addition of headlines and pictures. In that way, the classified advertisement has in reality advertisement. This is particularly true of real estate advertising?

Psychologists take opposing views of how external rewards, from warm praise to old cash, affect motivation and creativity. Behaviorists, who study the relation between actions and, argue that rewards can improve performance at work and school. Some other researchers who study various aspects of mental life, maintain those rewards often destroy creativity byencouraging dependence on approval and gifts from others. The latter view has gained many supporters, especially among educators. But the careful use of small monetary rewards sparks in grade-school children suggesting that properly presented inducements indeed aid inventiveness, according to a study in the June Journal Personality and Social Psychology.

“If they know they're working for a r eward and can focus on a relatively challenging task, they show the most creativity,” says Robert Esenberger of the University of Delaware in Newark. “But it's easy to kill creativity by giving rewards for poor performance or creating too much anticipation for rewards.”

A teacher who continually draws attention to rewards or who hands out high grades for ordinary achievement ends up with uninspired students, Esenberger holds. As an example of the latter point, he notes growing efforts at major universities to tighten grading standards and restore falling grades.

In earlier grades, the use of so-called token economics, in which students handle challenging problems and receive performance-based points toward valued rewards, shows promise in raising effort and creativity, the Delaware psychologist claims.

1. Psychologists are divided with regard to their attitudes toward ____.

A) the choice between spiritual encouragement and monetary rewards

B) the appropriate amount of external rewards

C) the study of relationship between actions and

D) the effects of external rewards on students' performance

2. What is the view held by many educators concerning external rewards for students?

A) They approve of external rewards.

B) They don't think external rewards.

C) They have doubts about external rewards.

D) They believe external rewards can motivate small children, but not college students.

3. According to the result of the study mentioned in the passage, what should educators do to stimulate motivation and creativity?

A) Give rewards for performances which deserve them.

B) Always promise rewards.

C) Assign tasks which are not very challenging.

D) Be more lenient to students when mistakes are made.

4. It can be inferred from the passage that major universities are trying to tighten their grading standards because they believe ____.

A) rewarding poor performance may kill the creativity of students’

B) punishment is more effective than rewarding

C) failing uninspired students helps improve their overall academic standards

D) discouraging the students anticipation for easy rewards is matter of urgency 5．Which of the following facts about “token economics” is not correct?

A) Students are assigned challenging tasks.

B) Rewards are given for good performances.

C) Students are evaluated according to the effort they put into the task.

D) With token economics, students’ creativity can be enhanced.

答案与解析：

1. D

心理学家认为外界的奖励对学生会有不同的影响。事实辨析题。根据文章第一句话“Psychologists take opposing views of how external re wards, from warm praise to old cash, affect motivation and creativity”可知，心理学家的分歧在于来自外界的奖励对学生的积极性和创造性究竟有什么影响，故选项D正确.

2. C

许多教育家对外界的奖励持怀疑态度。

文章第二段第一句话提到，后一种观点得到了许多教育工作者的支持，从第一段中可知，后一种观点是：奖励会促使学生对别人的赞许和馈赠产生依赖心理，因此奖励会破坏创造精神。由此可知，他们对奖励的正面作用持怀疑态度。故选项C正确。

3. A

根据文中的研究结果表明，教育家通过给予学生应得的奖励来提高他们的积极性和创造性。文章第三段指出，给予学生恰当的奖励，可使他们发挥更大的创造性，但如果对糟糕的表现也给予奖励，或让学生对奖励有太多的期许，反而会扼杀创造性。故选项A正确。

4. B

从文中可以得知，一些重点大学试图加强等级标准，因为他们相信惩罚比奖励更有效。事实辨析题。从文中第四段可知，许多大学之所以严格考试的评分标准，是因为“A teacher ... who hands out high gr ades for ordinary achievement ends up with uninspired students”。选项B 与此意相同。

5. C

根据学生的表现对他们作出评价。事实辨析题。根据最后一段的意思，在这种奖励制度下，要根据学生的表现对他们做出评价，而不仅仅是他们花费了多少精力来完成任务，故选项C正确。

When a consumer finds that an item she or he bought is faulty or in some other way does not live up to the manufacturer's claims, the first step is to present the warranty, or any other records which might help, at the store of purchase. In most cases, this action will produce results. However, if it does not, there are various means the consumer may use to gain satisfaction. A simple and common method used by many consumers is to complain directly to the store manager. In general, the “higher up” his or her complaint, the faster he or she can expect it to be settled. In such a case, it is usually settled in the consumer's favor, assuming he or she has a just claim. Consumers should complain in person whenever possible, but if they cannot get to the place of purchase, it is acceptable to phone or write the complaint in a letter. Complaining is usually most effective when it is done politely but firmly, and especially when the consumer can demonstrate what is wrong with the item in question. If this cannot be done, the consumer will succeed best by presenting specific information as to

what is wrong, rather than by making general statements. For example, “The left speaker does not work at all and the sound coming out of the right one is unclear” is better than “This stereo does not work”. The store manager may advice the consumer to write to the manufacturer. If so, the consumer should do this, stating the complaint as politely and firmly as possible. If a polite complaint does not achieve the desired result, the consumer can go to a step further. She or he can threaten to take the seller to court or report the seller to a private or public organization responsible for protecting consumer's rights.

1. When a consumer finds that his or her in it, the first thing he or she should do is to ____.

A) complain personally to the manager

B) threaten to take the matter to court

C) write a firm letter of complaint to the store of purchase

D) show some written proof of the purchase to the store

2. How can a consumer make his or her complaint more effective, according to the passage?

A) Explain exactly what is wrong with the item.

B) Threaten to take the seller to court.

C) Make polite and general statements about the problem.

D) Avoid having direct contact with the store manager.

3. According to the passage, which of the following is suggested as the last alternative that consumers may turn to?

A) Complain to the store manager in person.

B) Complain to the manufacturer.

C) Write a complaint letter to the manager.

D) Turn to the Consumers’ Rights Protection Organization for help.

4. The phrase “live up to” in this context means ____.

A) meet the standard of

B) realize the purpose of

C) fulfill the demands of

D) keep the promise of

5．The passage tells us ____.

A) how to settle a consumer’s complaint about a faulty item

B) how to make an effective complaint about a faulty item

C) how to avoid buying a faulty item

D) how to deal with complaints from customers

答案与解析：

The table before which we sit may be, as the scientist maintains, composed of dancing atoms, but it does not reveal itself to us as anything of the kind, and it is not with dancing atom s but a solid and motionless object that we live. So remote is this “real” table——and most of the other “realities” with which science deals——that it cannot be discussed in terms which have any human value, and though it may receive our purely intellectual credence it cannot be woven into the pattern of life as it is led,

in contradistinction to life as we attempt it. Vibrations in the ether(以太) are so totally unlike the color, purple that the gulf between them cannot be bridged, and they are, to

all intents and purposes，not one but two separate things of which the second and less “real” must be the most significant for us. And just as the sensation which has led us to attribute all objective reality to a non-existent thing which we called “purple”is more important for human life than the conception of vibrations of a certain frequency; so too the belief in God; however ill founded, has been more important in the life of man than the germ theory of true the latter may be.

We may, if we like, speak of consequence, as certain mystics love to do, of the different levels or orders of truth. We may adopt what is essentially a Platonistic (布拉图式的) trick of thought and insist upon postulating the existence of external realities which correspond to the needs and modes of human feeling and which, so we may insist, have their being in some part of the universe unreachable by science. But to do so is to make an unwarrantable assumption and to be guilty of the metaphysical fallacy of failing to distinguish between a truth of feeling and that other sort of truth which is described as “truth of correspondence” and it is better perhaps, at least for those of us who have grown up in thought, to steer clear of such confusions and to rest content with the admission that, though the universe with which science deals is the real universe, yet we do not and cannot have any but fleeting and imperfect contacts with it; that the most important part of our lives-our sensations, emotions, desires and aspirations-take place in a universe of illusions which science can attenuate or destroy, but which it is powerless to enrich.

1. The author suggests that in order to bridge the puzzling difference between scientific truth and the world of illusion, the reader should____.

A) try to rid himself of his world of illusion

B) accept his words as being one of illusion

C) apply the scientific method

D) learn to acknowledge both

2. Judging from the ideas and tone of the selection, one may reasonably guess that the author is ____.

A) a humanist B) a pantheist C) a nuclear physicist D) a doctor of medicine

3. According to this passage, a scientist would conceive of a “table” as being ____.

A) a solid motionless object

B) certain characteristic vibrations in “ether”

C) a form fixed in space and time

D) a mass of atoms in motion

4. The topic of this selection is____.

A) the distortion of reality by science

B) the confusion caused by emotions

C) Platonic and contemporary views of truth

D) the place of scientific truth in our lives

5. By “objective reality” (Last line, Para. 1) the author means____.

A) scientific reality

B) a symbolic existence

C) the viewer's experience

D) reality colored by emotion

答案与解析：

1. B

大学英语四级阅读理解训练（五）

Merchant and passenger ships are generally required to have a life preserver for every person aboard and in many cases, a certain percentage of smaller sizes for children. According to United States requirements, life preservers must design, reversible capable of being quickly adjusted to fit the uninitiated individual, and must be so designed as to support the wearer in the water in an upright or slightly backward position.

Sufficient buoyancy(浮力) to support the wearer should be retained by the life preserver after 48 hours in the water, and it should be reliable even after long period of storage. Thus it should be made of materials resistant to sunlight, gasoline, and oils, and it should be not easily set on fire.?The position in which the life preserver will support a person who jumps or falls into the water is most important, as is its tendency to turn the wearer in the water from a face-down position to an upright or slightly backward position, with his face clear of the water, even when the wearer is exhausted or unconscious.

The method of adjustment to the body should be simple, and self-evident to uninitiated persons even in the dark under the confused conditions, which follow a disaster. Thus, the life be reversible that it is nearly impossible to get it on wrong. Catches, straps, and ties should be kept to a minimum. In addition, the life preserver must be adjustable to the wide variety of shapes and sizes of wearers, since this greatly affects the position of floating and the self-righting qualities. A suitable life also be comfortable to wear at all times, in and out of the water, not so heavy as to encourage to take it off on shipboard while the ship is in danger, nor so burdensome that it hinders a person in the water while trying to swim.

1. The passage is mainly about____.

A) the uses of life preservers

B) the design of life preservers

C) the materials for life preservers

D) the buoyancy of life preservers

2. According to the passage, a life be first of all ____.

A) adjustable B) comfortable C) self-evident D) self-righting

3. United States Coast Guard does NOT require the life preserver to be made ____.

A) with as few strings as possible

B) capable of being worn on both sides

C) according to each wearer's size

D) comfortable and light to wear

4. By “the uninitiated individual” (Para. 1, Line. 4) the author refers to the person ____.

A) who has not been instructed how to use a life preserver

B) who has a little experience in using a life preserver

C) who uses a life preserver without permission

D) who becomes nervous before a disaster

5. What would happen if a person were supported by the life preserver in a wrong position?

A) The waves would move him backwards.

B) The water would choke him.

C) He would immediately sink to the bottom.

D) He would be exhausted or unconscious.

答案与解析：

大学英语四级阅读理解训练（六）

There is evidence that the usual variety of high blood pressure is,in part,a familiar disease.Since families have similar genes as well as similar environments,familiar diseases could be due to shared genetic influences,to shared environmental factors,or to both.For some years,the role of one environmental factor commonly shared by families,namely dietary salt(i.e.,sodium chloride),has been studied at Brookhaven National Laboratory.These studies suggest that chromic excess salt ingestion can lead to high blood pressure in man and animals.Some individuals,however,and some rats consume large amounts of salt without developing high blood pressure.No matter how strictly all environmental factors were controlled in these experiments,some salt-fed animals never developed hypertension whereas a few rapidly developed very severe hypertension followed by early death.These marked variations were interpreted to result from differences in genetic constitution.

By mating is successive generations only those animals that failed to develop hypertension from salt ingestion,a resistant strain(the "R" Strain)has been evolved in which consumption of large quantities of salt fails to influence the blood pressure significantly.In contrast,by mating only animals that quickly develop hypertension from salt,a sensitive strain("S" strain)has also been developed.

The availability of these tow strains permits investgations not heretofore possible.They provide a plausible laboratory model on which to investigate some clinical aspects of the human prototypes of hypertension.More important,there might be the possibility of developing methods by which genetic susceptibility of human beings to high blood pressure can be defined without waiting for its appearance.Radioactive sodium 22 was an important "tool" in working out the characteristics of the sodium chloride metabolism.

1.The study of the effects of salt on high blood pressure was carried out ______.

a.as members of the same family tend to use similar amounts of salt

b.to explore the long-term use of a sodium based substance

c.because it was proven that salt caused high blood pressure

d.because of the availability of chemically pure salt and its derivatives

2.The main difference between "S" and "R" rats is their ______.

a.need for sodium 22

b.rate of mating

c.reaction to salt

d.type of blood

3.We can infer from the article that sodium 22 can de used to ______.

a.control high blood pressure

b.cure high blood pressure caused by salt

c.tell the "S" rats from the "R" rats

d.determine what a sodium chloride metabolism is like

4.The most beneficial results of the research might be ______.

a.development of diets free of salt

b.an early cure for high blood pressure

c.control of genetic agents that cause high blood pressure

d.the early identification of potential high blood pressure victims

5.Which of the statements best relates the main idea of this article?

a.When salt is added rats and human beings react similarly.

b.The near future will see a cure for high blood pressure.

c.The medical field is desperately in need of research.

d.A tendency toward high blood pressure may be a hereditary factor.

大学英语四级阅读理解训练（八）

Social change is more likely to occur in societies where there is a mixture of different kinds of people than in societies where people are similar in many ways. The simple reason for this is that there are more different ways of looking at things present in the first kind of society. There are more ideas, more disagreements in interest, and more groups and organizations with different beliefs. In addition, there is

usually a greater worldly interest and greater tolerance in mixed societies. All these factors tend to promote social change by opening more areas of life to decision. In a society where people are quite similar in many ways, there are fewer occasions for people to see the need or the opportunity for change because everything seems to be the same. And although conditions may not be satisfactory, they are at least customary and undisputed.

Within a society, social change is also likely to occur more frequently and more readily in the material aspects of the culture than in the non-material, for example, in technology rather than in values; in what has been learned later in life rather than what was learned early; in the less basic and less emotional aspects of society than in their opposites; in the simple elements rather than in the complex ones; in form rather than in substance; and in elements that are acceptable to the culture rather than in strange elements.

Furthermore, social change is easier if it is gradual. For example, it comes more readily in human relations on a continuous scale rather than one with sharp dichotomies. This is one reason why change has not come more quickly to Black Americans as compared to other American minorities, because of the sharp difference in appearance between them and their white counterparts.

1.The passage is mainly discussing __________ .

a.the necessity of social change

b.certain factors that determine the ease with which social changes occur

c.two different societies

d.certain factors that promote social change

2.______ is one of the factors that tend to promote social change.

a.Joint interest

b.Different points of view

c.Less emotional people

d.Advanced technology

3.According to the passage, which of the following is NOT true?

a.Social change tends to meet with more difficulty in basic and emotional aspects of society.

b.Disagreement with and argument about conditions tend to slow down social change.

c.Social change is more likely to occur in the material aspect of society.

d.Social change is less likely to occur in what people learned when they were young.

4.The expression "greater tolerance"(paragraph 1) refers to _____ .

a."greater willingness to accept social change"

b."quicker adaptation to changing circumstances"

c."more respect for different beliefs and behavior"

d."geeater readiness to agree to different opinions and ideas"

5.Social change is less likely to occur in a society where people are quite similar in many ways because ________ .

a.people there have got so accustomed to their conditions that they seldom think it necessary to change

b.people there have identical needs that can be satisfied without much difficulty

c.people there are easy to please

d.people there are less disputed

We have not been able to investigate, at first hand, all our Independent Centers during the last season but all have been visited during the past three seasons. Should you need any more information about these centers we will try to get it for you. Our American centers have been investigated on our behalf by United Airlines Tours Department and by the U. S. tour operators who are assisting United and ourselves to offer you this novel program to the United States.

Where possible we have eliminated the use of superlatives from the text (possibly making our brochure(小册子) less attractive to read than it might be) and have concentrated on as accurate a description as possible. Nevertheless you should bear in mind that your opinion and the opinion of our investigator might differ and there may be changes between the time of a visit by our investigator and the visit of one of our customers.

We trust that it is evident to you that we have done all in our power to eliminate misdescription and that there really is no question of misrepresenta-tion on our part—either careless or otherwise. We welcome your constructive criticism—it is the best way we know of improving our brochures and our

service. Although complaints are very expensive to handle, your complaint or criticism will be thoroughly investigated and a refund (退赔) made if it is justified—none will be made if it isn"t.

英语四级阅读理解练习题 第94组

洛基英语，中国在线英语教育领导品牌 综合题，请根据题目给出的内容，来回答下面给出的试题。An unidentified wit once said, "laugh, and the world laughs with you. Snore, and you sleep alone." Yet snoring is far from a laughing matter, as those unfortunates with good hearing, who are rightly subjected to the sounds of the snoring disorder, will testify. It has been estimated that one of eight Americans snores; this means that there are approximately 21 million people --- women as well as men - who render an unpleasant sound when they are asleep. And assuming that each snorer disturbs the sleep of at least one other person, it necessarily follows that there are 21 million unhappy listeners. While a sleeping person breathes, either in or out, several structures in his nose and throat generate the snoring. The sounds, coming from the soft palate and other soft structures of the throat, are caused by vibratory responses to inflowing and outflowing air. When the soft tissues of the mouth and throat come close to the lining of the throat, the vibrations that occur are caused by the position of the tongue. In short, the noise made by snoring can be compared to the noise when breezes flutter a flag on a pole. The frequency of the vibrations depends on the size, density, and elasticity of the affected tissues and on the force of the air flow. Although it is usually the process of in haling or exhaling through the mouth that cause snoring, short snores come from the nose of an open-mouthed sleeper. In all fairness to snorers, however, it should be emphasized that snoring is an involuntary out which stops as the offender is awakened. 请根据上面给出的内容，来回答下面的单项选择题（下列每小题备选答案中，只有一个符合题意的正确答案。每小题0分，共5题。）16. If each snorer disturbs the sleep of one other person,the number of Americans that are unfortunately subjected the sound of the snores will be _____. A ：one out of five B ：one out of eight C ：eight out of one hundred D ：one out of eighteen 请选择答案：A:B:C:D:17. The snoring is caused by _____. A ：the soft palate and other structures of the throat B ：the inflwoing and outflwoing air through the nose C ：the inflowing and outflowing air throught mouth D ：the vibrations as a result of the inflwoing and outflowing air 请选择答案：A:B:C:D:18. If a person produces short snores,most probably he has _____. A ：a soft palate B ：a big nose

2019英语四级考试阅读理解练习20篇(4)

2019英语四级考试阅读理解练习20篇（4） 文化背景对商业运作的影响 Culture is one of the most challenging elements of the international marketplace. 『This system of learned behavior patterns characteristic of the members of a given society is constantly shaped by a set of dynamic variables： language, religion, values and attitudes, manners and customs, aesthetics, technology, education, and social institutions.』① To cope with this system, an international manager needs both factual and interpretive knowledge of culture. To some extent, the factual knowledge can be learned; its interpretation comes only through experience. The most complicated problems in dealing with the cultural environment stem from the fact that one cannot learn culture—one has to live it. Two schools of thought exist in the business world on how to deal with cultural diversity. One is that business is business the world around, following the model of Pepsi and McDonald’s. In some cases, globalization is a fact of life; however, cultural differences are still far from converging. The other school proposes that companies must tailor business approaches to individual cultures. Setting up policies and procedures in each country has been compared to an organ transplant; the critical question centers around acceptance or rejection. The major challenge to the international manager is to make sure that rejection is not a result of cultural myopia or even blindness.

As the pace of life continues to increase ,we are fast losing the art of relaxation. Once you are in the habit of rushing through lift,being on the go from morning till night, it is hard to slow down. But relaxation is essential for a healthy mind and body. Stress is an natural part of everyday lift and there is no way to avoid it. In fact ,it is not the bad thing it is often supposed to be .A certain amount of stress is vital to provide motivation adn give purpose to life. It is only when the stress gets out of control that it can lead to poor performance and ill health. The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress,and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress,in whatever form,we react both chemically and physically. In fact we make choice between "fight" or "flight" and in more primitive days the choice made the difference between life or death. The crises we meet today are unlikely to be so extreme,but however little the stress,it involves the same response. It is when such a reaction lasts long,through continued exposure to stress,that health becomes endangered.Such serious conditions as high blood pressure and heart disease have established links with stress.Since we cannot remove stress from our lives(it would be unwise to do so even if we could),we need to find ways to deal with it. 1.People are finding less and less time for relaxing themselves because_____. a.they do not know how to enjoy themselves b.they do not believe that relaxation is important for health c.they are travelling fast all the time d.they are becoming busier with their work 2.According to the writer ,the most important character for a good manager is his ________. a.not fearing stress b.knowing the art of relaxation c.high sense of responsibility d.having control over performance 3.Which of the follwing statements is ture? a.We can find some ways to avoid stress b.Stress is always harmful to people

We feel that there are many disadvantages in streaming(把......按能力分班) pupils. It does not take into account the fact that children develop at different rates. It can have a bad effect on both the bright and the not-so-bright child. After all, it can be quite discouraging to be at the bottom of the top grade! Besides, it is rather unreal to grade people just according to their intellectual ability. This is only one aspect of their total personality. We are concerned to develop the abilities of all our pupils to the full, not just their academic ability. We also value personal qualities and social skills, and we find that mixed-ability teaching contributes to all these aspects of learning. In our classrooms, we work in various ways. The pupils often work in groups: this gives them the opportunity to learn to co-operate, to share, and to develop leadership skills. They also learn how to cope with personal problems as well as learning how to think, to make decisions, to analyse and evaluate, and to communicate effectively. The pupils learn from each other as well as from the teacher. Sometimes the pupils work in pairs; sometimes they work on individual tasks and assignments, and they can do this at their own speed. They also have some formal class teaching when this is appropriate. We encourage our pupils to use the library, and we teach them the skills they need in order to do this efficiently. An advanced pupil can do advanced work: it does not matter what age the child is. We expect our pupils to do their best, not their least, and we give them every

2020年英语四级阅读理解练习题及解析(1) Passage 1 In the old days,children were familiar with birth and death as part of life. This is perhaps the first generation of American youngsters (年轻人)who have never been close by during the birth of a baby and have never experienced the death of a family member. Nowadays when people grow old, we often send them to nursing homes. When they get sick，we transfer them to a hospital, where children are forbidden to visit terminally ill patients—even when those patients are their parents. This deprives (剥夺)the dying patient of significant family members during the last few days of his life and it deprives the children of an experience of death, which is an important learning experience. Some of my colleagues and I once interviewed and followed approximately 500 terminally ill patients in order to find out what they could teach us and how we could be of more benefit,not just to them but to the members of their families as well. We were most impressed by the fact that even those patients who were not told of their serious illness were quite aware of its potential outcome. It is important for family members, and doctors and nurses to understand these patients’ communications in order to truly understand their needs，fears，and fantasies (幻想). Most of our patients welcomed another human being with whom they could talk openly, honestly，and frankly about their trouble. Many of them shared with us their tremendous need to

3 大学英语四级阅读理解试题及答案（四） 十六 Trees should only be pruned when there is a good and clear reason for doing so and , fortunately,the number of such reasons is small. Pruning involves the cutting away of obergrown and unwanted branches, and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way. First, pruning may be done to make sure that trees have a desired shape or size. The object may be to get a tree of the right height, and at the same time to help the growth of small side branches which will thicken its appearance or give it a special shape. Secondly, pruning may be done to make the tree healthier. You may cut diseaed or dead wood, or branches that are rubbing against each other and thus cause wounds. The health of a tree may be encouraged by removing branches that are blocking up the centre and so preventing the free movement of air. One result of pruning is that an open wound is left on the tree and this provides an easy entry for disease, but itis a wound that will heal. Often there is a race between the healing and the desease as to whether the tree will live or die, so that there is a period when the tree is at risk. It should be the aim of every gardener to reduce which has been pruned smooth and clean, for healing will be slowed down by roughness. You should allow the cut surface to dry for a few hurs and then paint it with one of the substances available from garden shops produced especially for this purpose. Pruning is usually without interference from the leaves and also it is very unlikely that the cuts yu make will bleed. If this does happen,it is, of course,impossible to paint them properly. 1.Pruning should be done to ______. a.make the tree grow taller
